‍Aino is the daughter of an illustrious line of song mages, but in Kalevala, magic is forbidden to women. So she spends her days weaving to support her fatherless family and only dares to sing in stolen moments in the forest. Sometimes, she even glimpses Oksi, the dread bear haunting Kalevala’s forests.

Meanwhile, Aino’s mercurial brother aspires to be a wizard. When he rashly challenges Väinö, the tyrannical lord of Kalevala, to a duel of song, Aino’s brother is defeated and promises Aino to Väinö as a bride to save his life. Aino refuses her fate and flees to a nearby lake to seek oblivion.

There Oksi finds her and reveals herself as a woman under Väinö’s curse. Oksi offers Aino a new life in the wilderness, and with nothing left to lose, she accepts. To Aino’s surprise, Oksi is thoughtful and warmhearted, and as the two young women fight for survival, their tentative bond only grows stronger.

But pacts of song are not so easily broken. And if Aino is to protect her family and freedom, she must forget all she has ever known and become what she was born to be: a witch. ‍
